look on Line 30 of your tax return? is there $2800 listed there? that is saying you didn't receive the 3rd stimulus payment but the IRS says you did.
did you receive $250 per month for 6 months for the advance child tax credit? That is $1500 and if you didn't list it on your tax return, your refund is inflated by the same amount.
So $2800 and $1500 = $4300 that was sent to you back in 2021, so it can't be requested a 2nd time on the tax return.
all just a hunch on what occured.
